28” CURL BAR ATTACHMENT A curl-bar cable attachment is one of several must-have attachments for gym owners with cable machines and functional trainers, all of which can be purchased from BOLT’s online store. Curl bars are primarily used to train the muscles of the arms through a variety of pulling and pushing motions. Attach your curl bar attachment to a cable that offers vertical resistance for pronated (palms facing down) and supinated (palms facing up) bicep curls and triceps extensions. The bar can also be attached to cables that offer horizontal resistance for close-grip cable rows. This particular curl bar, The BOLT 28-Inch Curl Bar Attachment, features light knurling on the inside and outside grips, is made of solid steel, and weighs 9 pounds.
